2016 Toyota Tacoma Engine Problems

Your truck's upper intake manifold flap actuator can break and cause the engine to enter limp mode, making your vehicle suddenly lose power while driving on the highway — particularly when accelerating or going uphill at higher speeds. This creates a serious safety risk since other vehicles may not expect you to suddenly slow down. The check engine light will appear, but the error code may disappear when you restart the engine, giving a false impression that the problem has resolved itself. The broken actuator must be completely replaced, as it cannot be repaired.

Your truck developed a noticeable oil leak around 58,850 miles, which the dealership confirmed was caused by a leak from the front seal or timing cover—a known issue requiring engine removal for repair. The repair cost over $5,700 out of pocket, and without the oil leak warning light, you risked running out of oil and being stranded. Fixing this type of oil leak typically requires removing the engine to access and replace the front seal or timing cover.

Your 2016 Tacoma has experienced leaking coolant from the crossover pipe and leaking oil from the timing chain cover—both requiring extensive engine work costing thousands of dollars to repair. These are known issues affecting 2016 and newer Tacomas with the 3.5L V6 engine, and Toyota has not issued a recall or extended warranty coverage. The leaks can cause overheating and oil loss, creating potential engine damage. Repairs typically require partial or full engine disassembly to access and replace the leaking components.

Your engine is leaking coolant, which can cause your engine to overheat if not addressed. You should have the cooling system inspected to find and fix the source of the leak. The repair may involve replacing a leaking hose, gasket, or the water pump.

Your engine has a coolant leak coming from the rear coolant bypass joint, which is a pipe that helps regulate engine temperature. You may notice coolant pooling under your truck or a sweet smell near the engine. If the leak gets worse, your engine could overheat. The fix will likely involve replacing the leaking bypass joint or resealing the connection.

Fuel injector(s) leaked without any warning, causing engine to loose power on freeway. We were fortunate to be able to move over to the shoulder before the truck lost all power. Vehicle was towed to dealer and it was determined that the injector leaked fuel into engine causing engine failure. Repairs needed include engine block, heads sub assembly, injectors and assorted other parts total for parts and labor $19,256 No warning lights or symptoms prior to this problem. Truck has been running fine with no problems, only has 41,000 miles.

This vehicle is equipped with Toyota V6 Motor that was new in 2016. The issue is the Timing Chain Cover leaks oil. This was an issue on Toyota Motors before 2016 and Toyota issued a TSB for those. However Toyota has refused to acknowledge this ongoing issue in its post 2016 Motors. This is a very well know issue by Toyota.

driving full speed car suddenly slows and light on dash reads accelerator and brake pressed at same time, although my foot is nowhere near the brake. This is 3rd time it has happened, Toyota say's it doesn't come up as error on their computer.

There is a known factory defect on a robotic seal around the engine block, in which the robot misses a half inch piece of the engine block, causing oil seepage and leaking of engine oil. The problem is on dozens of Toyota forums and I have also consulted with two different dealerships that have verified this. The 4 cylinder engines in the Tacoma have already been recalled for this issue but they are offering no reimbursement or recall on the 6 cylinder engines. The engine begins leaking oil early in it its life as mine has been. An engine should not fail at 20k 30k or 80k miles due to a factory defect. Toyota should be offering a fix for this issue as it will significantly cut the life of rhe engine. This can cause engine fire and various other safety issues in these trucks if enough engine oil leaks down into a hot engine.

WHILE DRIVING ON THE FREEWAY, THE VEHICLE STARTED LURCHING AND LOOSING POWER THEN ABRUPTLY SHUT OFF.

HESITATION UPON ACCELERATION AT TIMES.

AS OF NOW THE AC FAN MAKES A LOUD NOISE LIKE SOMETHING FELL APART. THERE IS NO AIR BLOWING THROUGH THE VENTS. IT SOUNDS LIKE BROKEN BLOWER MOTER.

WHEN MY A/C STOPPED WORKING DURING THE WARRANTY PERIOD, I HAD IT CHECKED AT GLENS FALLS TOYOTA WHERE I WAS TOLD THE CONDENSOR NEEDED REPLACEMENT. THEY DETERMINED THAT THE HOLE HAD BEEN CAUSED BY A ROCK KICKED UP BY THE VEHICLE AND THAT IT WOULD NOT BE COVERED UNDER WARRANTY. I AM CONCERNED ABOUT THIS POLICY, AS THERE ARE MANY OTHER ENGINE COMPONENTS THAT - LIKE THE A/C CONDENSOR - ARE NOT SHIELDED ON THIS OFF-ROAD CAPABLE VEHICLE. MY VEHICLE HAS NEVER BEEN DRIVEN OFF-ROAD.

BROUGHT VEHICLE IN TO DEALERSHIP( NORTHWAY TOYOTA) FOR RECALL NOTICE, AND VEHICLE STALLING. THEY SUPPOSEDLY REPAIRED IT, BUT VEHICLE IS DOING THE EXACT SAME THING, STALLING AND MALFUNCTION INDICATORS ARE ON. CONTACTED THE DEALERSHIP BUT NO ONE WILL RETURN MY CALL. I DON'T THINK THEY DID ANYTHING TO MY VEHICLE THE FIRST TIME.

CRANK POSITION SENSOR-TRUCK WAS IN MOTION ON A CITY STREET WHEN IT BUCKED AND STALLED. IT STARTED AGAIN AND I WAS ABLE TO MAKE IT A BLOCK TO MY MOM'S HOUSE/GARAGE, WHERE I KEEP MY TRUCK. AS I WAS PULLING INTO THE GARAGE, IT BUCKED AND STALLED AGAIN. I REPLACED THE CPS (CRANK POSITION SENSOR) BECAUSE I DIDN'T WANT MY TRUCK TOWED TO THE DEALERSHIP. IT COST ME $110 BUCK. I'M REALLY GLAD I WASN'T OUT CAMPING OR IN TRAFFIC WHEN THIS OCCURRED, AS IT COULD HAVE BEEN A MUCH WORSE SITUATION.
